The Standard Gage 00534020 digital caliper measures 0 - 6 inches and 0 to 150 mm with 0.0005” and 0.02 mm accuracy and resolution to 0.0005 inches and 0.01 mm. It has a stainless steel beam and slide for corrosion resistance and to help extend caliper life, thumb roller for fine adjustments, 1.6 inches (40-mm) jaws, and includes a depth rod to allow for depth measurement in addition to the standard inner diameter (ID) and outer diameter (OD) measurements that most slide calipers can perform. The LCD display is easier to read than a vernier caliper.
The caliper can be used with one hand by operating the fine adjustment roll with the thumb. The single battery is accessible, on the front of the plastic casing next to the LCD. To zero the caliper at any position, use the zero button. Linear accuracy meets the international Deutsches Institut fur Normung 862: Vernier Calipers Requirements and Testing (DIN 862) standards. Approximate jaw depth for the outside measuring jaws is 1.6” (40 mm). This caliper comes in a fitted plastic case with inspection certificate to help ensure conformity to technical specifications.
Calipers measure the distance between two opposing sides of an object. They make inner diameter (ID), outer diameter (OD), depth, or step measurements, according to their type. Calipers are commonly used in architecture, metalworking, mechanical engineering, machining, manufacturing, carpentry, and medicine. The simplest calipers have two legs to mark the two points and require a ruler to take the measurement. More complex calipers use two sets of jaws instead of legs and have up to two graduated scales. Vernier, dial, and digital calipers give direct and accurate readings and are functionally identical, having a calibrated scale with a fixed jaw, and another jaw with a movable pointer that slides along the scale. The vernier caliper has a scale sliding parallel to the main scale for an additional, fractional reading to improve measurement precision. The dial caliper has a circular dial with a pointer on a toothed gear rack replacing the second vernier scale. As with the vernier, this second measurement is added to the reading from the main scale to obtain the result. The dial caliper is used also for measuring size differential between two objects. The digital caliper takes the same sort of differential measurements as the dial caliper by zeroing the display at any point along the slide, with an LCD (replacing the dial) that displays a single, easily read value in both English and metric units. Some digital calipers can hold data readings between measurements and send them to data collection devices.
